Deploying NSX Manager and attaching it to vCenter are the first steps in allowing you to deploy your software defined network. Your goal is to have logical switches, distributed logical routers, and create and enforce security policies with the distributed firewall and service composer.

Before you can reach your goal, you need to deploy our NSX Controllers and tell NSX Manager which ESXi hosts will be part of the NSX domain. The steps to tell NSX Manager which ESXi hosts will be part of the NSX Domain are

Install NSX modules.

Configure VXLAN networking in each ESXi host.

Create VNI pools.

Create transport zones.

This chapter covers all the steps needed to prepare your NSX domain. The chapter begins with a proper introduction of what VXLAN is.

Do I Know This Already?

The “Do I Know This Already?” quiz allows you to assess whether you should read this entire chapter or simply jump to the “Exam Preparation Tasks” section for review. If you are in doubt, read the entire chapter. Table 4-1 outlines the major headings in this chapter and the corresponding “Do I Know This Already?” quiz questions. You can find the answers in Appendix A, “Answers to the ‘Do I Know This Already?’ Quizzes.”
